摘要:

介绍了铁-硫氰酸根络合显色法测定NH4SCN含量的原理及操作步骤,同时对SO2-4、S2O2-3、S2-进行了干扰离子测试。该法具有操作简单、反应灵敏、准确性高等优点,能够快速检测脱硫液中NH4SCN的含量。

Abstract:

This paper described the principle and operating procedure for determination of NH4SCN content in desulfurization liquid by Fe-thiocyanic acid root complexing colorimetry and the test for interfering ion of SO42-,S2O32- and S2-.This method is proved to be simple in operation,sensitive in reaction and high in accuracy,which could rapidly determine the NH4SCN content in desulfurization liquid.
